Solution

1. Preparation

Ensure the vehicle is in park (or neutral) and the parking brake is engaged.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Terminals: Clean any corrosion from the battery terminals using a wire brush and a mixture of baking soda and water.
Reconnect Battery: Reconnect the negative terminal securely.
Battery Replacement (if needed):
1. Remove the battery hold-down bracket using a socket set.
2. Carefully lift out the old battery.
3. Place the new battery in the tray, ensuring it is properly oriented.
4. Reinstall the hold-down bracket and tighten.
5. Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Check

Starter Removal:
1. Disconnect the battery again for safety.
2. Remove any components obstructing access to the starter (e.g., air intake duct).
3. Unbolt the starter motor from its mounting using a socket set.
4. Disconnect the wiring harness from the starter.
Starter Test/Replacement:
1. Test the starter motor using a multimeter to check for proper function.
2. If defective, replace it with a new starter motor by reversing the removal steps.

4. Fuel System Check

Fuel Pump Operation:
1. Remove the access panel to the fuel pump (if applicable).
2. Check the fuel pump relay and fuse for continuity.
